TORONTO - Telus says it will begin offering a service to unlock mobile phones that use SIM cards starting next week.

The telecom company says that starting Feb. 15 its customers will be able to pay $50 to have their mobile phones unlocked -- a move that would allow the devices to work on other carrier's networks.

Telus said that means customers on long-term contracts, typically smartphone users, will be able to get their phones unlocked if they've had the device for a minimum of 90 days.

Typically, customers have to wait until the end of their contracts to get a phone unlocked or go to third-party retailer that provides the service.

Consumers can also buy SIM cards from Wind Mobile without purchasing a Wind phone, but the phone has to be unlocked and compatible with the Wind network.
